drduncan Posted April 15, 2020 Share Posted April 15, 2020 Has anyone discovered/produced drawings of the CMR iron bodied China clay tippler wagons? Or discovered close up images that they can share? My mixed gauge 1890-2 layout Nampara will need about 12 or more of these tiny little wagons.... Any help gratefully received. Duncan Link to post Share on other sites More sharing options...
MarcD Posted April 28, 2020 Share Posted April 28, 2020 Not seen a drawing for one have got a number of photos from different angles so using first principals you should be able to produce a drawing. I think that there might be two types. Dumb buffered at one end and sprung at the other and a more modern one with sprung buffers at each end. I presume you have both of John Vaughan's books?

drduncan Posted May 17, 2020 Author Share Posted May 17, 2020 Hi Mark, Sorry for the slow reply. Would you be willing to share your photos? Which Vaughan books? Got his one on West Country China clay trains... Regards Duncan Link to post Share on other sites More sharing options...
MarcD Posted May 25, 2020 Share Posted May 25, 2020 Hi Duncan I have attached some photos hope they help Marc Link to post Share on other sites More sharing options...
drduncan Posted May 26, 2020 Author Share Posted May 26, 2020 Marc, Very many thanks. That 3/4 view is especially fine. I’m sure those images will be exceptionally useful. Duncan Link to post Share on other sites More sharing options...

Duncan That book and its companion volume West Country China Clay Trains are, in my view, essential reference works if you are modelling the china clay lines or the railways of mid-Cornwall more generally.

MarcD Posted May 26, 2020 Share Posted May 26, 2020 There aren't many good photos out there with China clay wagons in. I have a drawing from the Matthews private owner wagon book of a board gauge clay wagon but I have never seen a photo. Marc Link to post Share on other sites More sharing options...
drduncan Posted May 26, 2020 Author Share Posted May 26, 2020 Yes I have the Matthew’s book and I’m not sure of the accuracy of the drawing... Duncan Link to post Share on other sites More sharing options...
drduncan Posted May 31, 2020 Author Share Posted May 31, 2020 Here is the first attempt at the drawing for the CMR tippler wagon. DrD 1 Link to post Share on other sites More sharing options...
MarcD Posted May 31, 2020 Share Posted May 31, 2020 Nice work what scale are you working in. Marc Link to post Share on other sites More sharing options...
drduncan Posted May 31, 2020 Author Share Posted May 31, 2020 Thanks. I’m 4mm/EM. I intend using etched w-irons and modified cast or plastic brake gear. Not sure about the curved brake lever - probably cut from 10thou styrene. DrD Link to post Share on other sites More sharing options...
MarcD Posted May 31, 2020 Share Posted May 31, 2020 Some of my fellow S7 modellers would cut the brake lever from plate brass or NS as a manufacturing engineer I would etch it. Marc Link to post Share on other sites More sharing options...
drduncan Posted June 7, 2020 Author Share Posted June 7, 2020 (edited) The prototype 3D print! The W irons are D & S. I think the buffers at the non tippling end should be self contained ones and I think I’ll modify GW self contained ones. Brake gear will be butchered coopercraft from the spares box. For the mark 2 I’m going to try extruding up the end door strapping to meet a 0.5mm brass wire hinge. I’m also going to do a later version with buffers at both ends which will have a slightly different side brace at the door end as per some prototype images.

MarcD Posted June 7, 2020 Share Posted June 7, 2020 Hi Duncan It looks very good. Couple of questions 1, what printer are you using? I ordered a elegoo Saturn yesterday. 2, what wall thickness are you printing the sides at? Marc Link to post Share on other sites More sharing options...

The longer the side the ticker due to possible warping. D Link to post Share on other sites More sharing options...
MarcD Posted June 7, 2020 Share Posted June 7, 2020 I would normally is 0.48mm etched brass for steel wagons. I did wonder if it would be stronger at a larger scale. shapeways recommends 0.8mm as minimum thickness. This could be a commercial reason not an engineering one.

MarcD Posted May 11, 2022 Share Posted May 11, 2022 How is the project going? I've started working on Carbean in S7 so I'm going to try to produce some in 7mm versions. I have found a set of dimensions for a CMR stone wagon of the same vintage and I was wondering if they were the same size? Marc Link to post Share on other sites More sharing options...
drduncan Posted May 14, 2022 Author Share Posted May 14, 2022 Hi Mark! I just need to add springs and axle boxes and they are ready for the paint shop. I decided to add brake gear and lever as part of the design rather than use butchered bits from the spares box. Regards, Duncan 2 1 Link to post Share on other sites More sharing options...
RMweb Gold Mikkel Posted May 14, 2022 RMweb Gold Share Posted May 14, 2022 That looks very good, rustic but stylish. I'll now get down from my handstand. 3 1 Link to post Share on other sites More sharing options...
MarcD Posted May 14, 2022 Share Posted May 14, 2022 I believe it is one on the ones shipped to Australia! 🤣🤣 But seriously it looks very good. What wheel base and LOH did you settle for? Did you use the dimensions from the stone wagon? Marc 1 Link to post Share on other sites More sharing options...
